Glad you found it, suprised nothing has come up with this before. Shame i gave up on the 4efte seive and have a slightly less sieve like car and engine
From looking at the replacement and not hearing anything about this before i dont think this is your issue. That seals sounds like its just there to protect the bearing.
Wish it worked, would have saved me a massive headache. Not easy to swap the matrix on a volvo! Would never use it on any car i was slightly bothered about
Anyone had any experience with this stuff? Heater matrix is leaking on the daily and its a £50 and around 10hr job to changed, for a £200 car it doesn't seem worth it. If its not going to work i will have to bite the bullet
